The Detection and Identification of Asbestos and Asbestiform Materials in Talc Harold D. Stanley and Robert E> Norwood Pfizer Inc.--Minerais, Pigments & Metals Division INTRODUCTION The pncumoconiolic and cancer inducing health hazards of exposure to asbestos and asbestiform minerals often found associated with talc have been appropriately identified by recent research and mass-media publica tions f 1-(i). Because of Pfizer's position as a supplier of talr to many industries, a reliable method of detecting and identifying asbestos and asbestiform minerals pos sibly present in the talc had to be developed. Ideally the technique should he simple and direct but above all it must he positive and unambiguous. la ic is a naturally occuring hydrous magnesium silicate having a general formula of Mg* (S i,,0JO) 2 Mg (O il);. The mineral, talc, is felt to be formed by the hydro- thermal alteration of serpentine and trcmolile. Talc can he derived from minerals containing various amounts of tremolile, Mg( ( ( 'a ;S i,, 0 ;;) Mg (OH)], chlorite, Mg4 ( Si K Mg (O il);, chrysolite Mg, (Si0;)*8M g (O H ),, and a group of rlirysolile-like minerals called amphiholcs or ashestlform minerals. Chief among these asbestiform minerals are anlhophyllite, (Mg.Fe**); -SiOj, (O il),, amoslle, (Mg.Fe*')7 S i,,O j, (OH)j, crocidolile, Na7Fe`\lF c '* 7 (SiR0 77) (OH); and actino- lite. Ca, (Mg,Fe``)s S i,O j, (OH);. From the above chemical formulas one can get an ap preciation for the interrelatedness of talc and the ashestos type minerals, particularly when one considers that the degree of replacement of one element for another is seldom in exact proportion. Although talc itself has not been shown to induce tire irreversible health problems (7). ils chemical near-neighbors have (8). The exact causes of the undersirable reactions of the human body when exposed to asbestiform minerals is not entirely clear at th time o f this writing but it is felt to be som e how linked to the fiborous nature o f the asbestos-like minerals. Currently available methods and methodology for detec ting asbestos, tremolile and the asbestiform minerals in the presence o f talc were reviewed. The three most likely candidates were: 1. Light microscopy 2. X-ray diffraction 3. Transmission electron microscopy Samples or "pure" laic and tremolile were obtained front various deposits owned by Pfizer Inc. Samples of pure and carefully characterized asbestos minerals were obtained from the International Union Against Cancer, (U.I.C.C.), Pneumoconiosis Research Unit, Llsndough Hospital, Penarth, Glamorgan, United Kingdom. The talcs and asbestiform minerals were examined in the pure nr as-received state, their characteristics noted and mixtures made to determine If detection of asbestiform minerals was possible at low levels and, if so, what the minimum detection levels might be. EXPERIMENTAL X-ray diffraction patterns were obtained for ail the minerals and mixtures used in this study employing the conventional technique o f scanning at rates o f 0.5 to 1.0 degrees 2 theta per minute. The samples were then subjected to scrutiny by optical and electron micros copy. During this procedure it was discovered that CRMC-LLF-Pfizer-Micro-000002 certain niixtiin siiiiil a'.ln".liform minerals by the conventional X-ray diffrac tion technique mentioned nhovr and the light microMii|tr exhibited fairly hire* percentages. (5'7 and more), of tm nnlile and/or ashrstifnmis when viewed in ill transmission electron microscope. Delineation of the reasons for Ibis paradox enabled us to develop reliable leebiiiques for delecting Iremnlite and the asbosllforms at the 0.25'; and 0.5% levels respeelively in most tales by X-ray diffraelion. Even lower levels of these minerals are detectable by transmission electron microscopy. X RAY DIFFRACTION The rispat-ings Tor tale, chlorite, tremolite and the asbestiform minerals are giien in Table 1. The values given in Table 1 are averaged values for pure materials and can shift as much as *0.2 / *0.3 Angstroms de pending upon sample preparation and/or level at which the constituent is found in the parent mineral matrix and the specimens conformity to the idealized chemical compositions. When attempting to detect tremolite and the asbestiform minerals in tale at concentrations of 5 '/ or below. It was found that the normal scanning rate of 0.5 to 1 degrees 2 theta per minute was not satisfactory for the following reasons: 1. The noise level is so high that a detection limit of .V; is (lie minimum possible. 2. II is difficult to accurately quantify data from a high noise level traring. In order lo avoid lliese difficulties, an automated step-Manning method was employed in which the diffractometer was moved in increments of 0.05 degrees 2 theta and the intensity of X-radiation at each step measured Tor a total of two minutes. An intensity versus degrees 2 Ibeta plot over the area of interest was obtained from a Wang 720 programmable calculator will* plotler/prinler output. Figures I and 2 show the step scan method plotted for tremolite. This method allowed the signal to noise ratio lo be raised suffi- inlcgralion technique. Calibration curves were estab lished by integrating thc area under the appropriate X-ray diffraction peak o f samples with i% to 1(1% additions o f the species under investigation to a sample of tale shown to be tremolite and asbestiform free by the method o f transmission electron microscopy out lined below. Examples o f these curves are shown in Figures 3 and 4. Extrapolation of these curves to zero percent addition yields the minimum amount o f the mineral that can be detected in the talc matrix. For tremolite in talc Ihc minimum detectable amount was found to be 0.25%. For chrysolite and the other asbestiforin minerals the minimum detectable level obtained by Ibis method is 0.5%, but this ran only be achieved in the absence o f chlorite. Attempts to remove the chlorite by a careful acid wash succeeded only in rendering the chrysotile amorphous to the X-ray beam with *he result that no X-ray spectrum was obtained in the chrysotile region. Further experimentation revealed that the presence o f tremolite at fairly low levels tended to mask or interfere with the detection o f some of the asbestiform minerals. It was thus clear that another technique would be needed in these special cases in order to be able to achieve an unambiguous analysis. ii & /Vi' fj/ t s fo k S a Aufrmvifpti u rp tr.mnini) *?*(?cufpd with X-ray diffraction. 1 Dispersion siaininq technique with light or optical microscopy. LIGHT MICROSCOPY Techniques employing the optical microscope have been used to identify mineral specimens for a long time. One of the more interesting and useftd of these techniques is the Cherkasov focal screening dispersion staining proce dure (9). This technique, often shortened to "Dispersion Staining," has been applied successfully to the identifica tion of asbestiform fibers ( 10.11).

The mor phology of the ashestiform minerals and tremolile is generally described as nrirular or fibrous.

The present work has shown that properly prepared samples of talc can be step-scanned by an X-ray diffractometer to delect tremolite at levels down to The lower detection limit of this technique is difficult of arcess since one is often dealing with individual rryslals. However, a typical field of view of a talc which was originally asbestos-free but now contained a 5% 0.25% and ashestiform minerals at the 0.5% level in the absence o f chlorite. In the presence o f chlorite and at concentration levels lower than those stated above, the transmission electron microscope was found to provide reliable detection and identification o f tremolite and ashestiform minerals. The transmission electron micro scope is the most sensitive method and appears to be a more or less referee technique since when morphology observations are coupled with selcrted area electron diffraction studies, there are no known interferences.

Talc is a naturally occurring hydrous magnesium silicate and you have been given the formulas from various and sundry people this morning and this afternoon; and is derived from minerals containing various amounts of tremolite, chlorite, chrysotile and a group of chrysotile-like minerals called amphiboles or asbestiform minerals. Chief among these are anthophyllite, amosite, crocidolite and actinolite. From their chemical formulas, which you can find in the reference, you can see the close chemical similarity between talc and these asbestos type minerals. It becomes particularly difficult to analyze for these when one considers that the degree of replacement of one ion for another is seldom in exact proportion. Often the best that you can do is say that,thls particular material is, for example, like anthophyllite or most like anthophyllite. We investigated the currently available methods and methodology for detecting asbestos and tremolite and the asbestiform minerals in the presence of talc. The three most likely candidates that we came up with were light microscopy, X-ray diffraction and transmission electron microscopy. Samples of pure talc and tremolite were obtained from various deposits owned by Pfizer. Samples of very pure and very carefully characterized asbestos minerals were obtained KKbh CRMC-LLF-Pfizer-Micro-000009 talc and asbestiform minerals were obtained in the pure, as received state, their characteristics noted and mixtures mode to determine if the detection of asbestiform minerals was possible at low levels and, if so, what might the minimum detection levels be7 Experimentally we started with X-ray diffraction. We obtained patterns for all of the minerals and mixtures used in the study employing the conventional X-ray techniques of scanning at rates of from 0.5 to 1 degrees 2 theta per minute. These samples were then subjected to scrutiny by optical and electron microscopy. When we did this we found that sometimes mixtures and mineral species shown to be free of asbestos minerals by the conventional X-ray diffraction techniques mentioned above and the light microscope also exhibited very large percentages of 5% or more of tremolite and/or asbestos minerals when viewed in the transmission electron microscope. We sought to find out the reason for this paradox which then enabled us to develop reliable techniques for detecting tremolite and the asbestiforms at 0.25% to 0.5% by X-ray diffraction. Even lower levels than these could be detected by electron microscopy. The first table, Table I, shows the d spacing for talc, chlorite, tremnJite and the asbestiform minerals. These are for pure minerals and can shift by as much as 0.2 to 0.3 angstroms depending on the sample preparation. You can see the problem that is going to present itself when you consider that you are really dealing with three specific items. You arc dealing with talc, you are dealing with chrysotile CRMC-LLF-Pfizer-Micro-000010 thrown in -- chlorite we did is use an ordinary Btep scanning diffractometer which moved the counter .05 degrees 2 theta and the intensity ;o*sthe X radiation at each step was measured for approximately 2 to U minutes. We then plotted the intensity of this versus 2 theta over the area of interest - roughly 13 degrees to 9 degrees 2 theta shown in.^igure 1. This is the type of output we obtained when we examined talc from our Montana deposit. The general upward slope as you go lover in degrees is caused by the measuring device entering the primary beam of the X-ray tube. We established calibration curves by integrating the areas under these curves and the appropriate X-ray diffraction peak, samples with as little as 0.1% and as much as 10% additions of the species under investigation vere examined. We extrapolated these curves to 0% and we got the minimum background with the minimum amount detectable using the standardized formula of 3 times the square root of background level at that point. For tremolite in talc, the minimum detectable level was found to be 0.25%. For chrysotile and other asbestiform minerals the minimum detectable level by this method is 0.5% but this can only be achieved in the absence of chlorite. Referring back to the first figure, the chlorite tends to mask the presence of chrysotile asbestos because it is so close to chrysotile asbestos in its major diffraction peak. The consequance of this is that when you have chrysotile asbestos or when you Imvo chlorite, you can't be sure* exactly which of the two you have. If you have a small amount of chlorite, it will very effectly CRMC-LLF-Pfizer-Micro-000011 chlorite is ticid soluble so we thought what we would do in this case was to acid wash the talc containing the chlorite, get rid of the chlorite and then examine it for chrysotile asbestos and in fact, the chrysotile asbestos peak and the chlorite peak both did disappear* The only problem was that when we looked at these samples in the electron \ microscope, the presence of the chrysotile fibers was still found. This is explained by the fact that chrysotile asbestos is in fact partially soluble in hydrochloric acid. It is a diffusion controlled reaction and as the magnesium ions depart from the crystal structure, you are left with a shell of silicon which is amorphous to the X-ray 3 beam - the X-ray beam does not see it. The electron microscope does pick it out. Figure 2 demonstrates the difference in X-ray intensity one gets over the same angular region when one adds 5% tremolite or 1% tremolite. The same type of plot is available when one adds chrysotile asbestos or any % of the other asbestiform minerals. Figure 3 is the calibration plot that, we obtained for chrysotile. Therefore, we can put a pretty good handle on the percent asbestos or tremolite or asbestiform mineral that we are going to find. Figure 1* is the calibration curve " obtained for tremolite. So you can see that it is a fairly sensitive technique and ir, easily performed. Table 2 shows the selected area electron diffraction maxima for talc, tremolite, chrysotile, amosite, nnthophyllite. We use these for the positive identification of these Y* minerals. Transmission electron microscopy is employed in this CRMC-LLF-Pfizer-Micro-000012 identification , , f,''ri " Y-f/l 'r"'. need to be unambiguous about our analysis. We want to 1 what we are looking at. The electron microscope has the ability to single out individual particles and by virtue of selected area electron diffraction, we can derive the same type of data as an X-ray diffraction unit except we are quite a bit more sensitive here. By virtue of its ability to exomine these individual fibers and particles at very high magnification, the transmission electron microscope has been found by us to provide the technique ancillary to X-ray diffraction that is needed to complete the unambiguous detection of the identification of asbestiform minerals. The morphology of the asbestiform ! minerals and tremolite is generally described as acicular or fibrous. This immediately serves to Isolate it from the pl&ty talc matrix even in the presence of chlorite since chlorite, fortunately closely M resembles the morphology of talc. The chlorite is platy; the talc is platy so that eliminates immediately the problem of detecting fibers since the investigator disregards all platy particles and looks only for fibers. How if a careful examination of approximately 100 different fields of view fails to reveal any fibrous material, M then we feel that talc is free of tremolite, chrysotile and the asbestiform minerals. The problem of particle curling was mentioned earlier. One of the uses for selected area electron diffraction is to diffract from curled up plates. You can tell that the diffraction pattern is no different from that of the plate from which this material starts to curl. With the transmission electron microscope, you are *--I i ' CRMC-LLF-Pfizer-Micro-000013 :;*. ;.r< .voTiF'.`%'.' :'i/W?a -v'':^ J & 's*' looking right into the particle :V *'' ' "*^ >0*4. from the pseudo fiber of curled up talc and you find that its pattern ie identical to that of the main talc body. Therefore, there is no difference mineralogically between the two. The talc pseudo fiber can ; Just as likely unroll as it can roll up. How at first we had a little problem with our talcs because when we used the Montana materia]., we couldn't find any fibers, we couldn't find any chrysotile, we couldn't find any tremolite, we couldn't find anything but a small bit of chlorite. This prompted us to spike some samples and we did this by adding a weighed amount of chrysotile asbestos in one case for example to a weighed amount of our talc and we were able to construct calibration curves similar to the type that we used in the X-ray diffraction work and ve found for example that with 1% addition of chrysotile asbestos to the Montana talc, we would find on the average in the 100 fields of view, 6 fibers with a standard deviation of approximately 1-1/2 fibers and it also followed a Guasian distribution which made us feel a good deal better about the homogeneity of the sample. These samples were prepared by slurrying the dry powders in a Waring blender with isoprophyl or ethyl alcohol for five minutes and then allowing them to dry and then Just simply crumbling them up. We also used 0.1% and 0.5# asbestos and up to 5%. Figure 6 is a typical example of Montana talc. The micron marker is 1 micron and these are all platy materials. There have been no fibers identified in thi material. Figure 5 shows a typical example when you spike the sample with 1# chrysotile asbestos. Fibers are readily observed. I call your attention to the thinness ' i CRMC-LLF-Pfizer-Micro-000014 of the fibers - I would' certainly tu r n a sample or naturally occurring talc with a naturally occurring chrysotile asbestos contaminant, the chrysotile running at on approximate 1<50 angle. These fibers will become individualized. They are pretty much individualized right there and they are also very thin. m We also tried light microscopy since the optical microscope has for many years been used to identify mineral species and one of the things we turned to was dispersion staining since that has been successfully applied to the identification of asbestiform fibers. There has been a great deal of work done on it and asbestiform minerals are in fact m readily distinguishable from one another. The difficulty in applying this to the problem at hand is that while it vorks well on pure samples of fairly massive fiber length from 3 to 5 microns, our observations by transmission electron microscopy have shown that naturally occurring asbestiform minerals often lie below the working resolution capabilities of the light microscope and furthermore while massive fiber bundles can often be observed by either light or electron microscopy the observation of individual fibers smaller than 0.5 by 0.2 micrometers often will require the high resolution capability of the transmission electron microscope. In addition, the limit of detection is confounded by the presence of talc fibers which are the thin talc plates curled up at the edge. Talc plates sitting on an edge also give difficulty. The lower limit of detection war. felt to be too high to be of commercial value. CRMC-LLF-Pfizer-Micro-000015 ... concliiiVIon, we feel tba* trie proptrly prepared nomples of talc cpin be step canned by X-ray diffraction to detect trcmollte down to a l/t of a percent, and an asbestiform mineral at the 1/2? level in the absence of chlorite. In the presence of chlorite arid at concentration levels lower than those stated above the transmission electron microscope was found to provide reliable detection in identification of tremolite and the aBbestiform minerals. . The transmission electron microscope is the most sensitive method and appears to be a more or less referee technique since when morphology observations are coupled with selected area electron diffraction studies, there are no known interferences. We found light.microscopy helpful only in scrutinizing samples with very large particles at very high concentrations of objectionable fibers. CRMC-LLF-Pfizer-Micro-000016 to G .

Under the conditions described in this paper the lower limit of detectability for treraolite is 0.25% and for chrysotile, 0.5%. The principal lattice spacings for chlorite at 7.03 d-spacing in Angstroms and 7.38 for chrysotile should be resolvable by using the curved graphite crystal on the X-ray diffracometer and very fine tuning of the optical system and the electronics.

Norwood, Research M a nager for Pfizer's Minerals, Pigments, and Metals Division and wi t h Harold D. Stanley, Jr.; Group Leader, Testing. This was a good meeting in that both Pfizer and J-M are essentially in agreement as to test methods and interpreta tion of data. They use all of the same procedures we do: XRD, TEM, SEM, DTA, TGA, etc. but seem to rely most heavily upon TEM and XRD. ::''kpf We showed them our data on samples of their CP talcs indica >m ting up to 30% tremolite by XRD. They couldn't understand this and we gave them portions of the same samples for testing. They promised to get back to Ed Fenner with their results. They had complete analytical data on three samples of Penhorwood which they recently obtained from some unknown source. By XRD they show no asbestos minerals. They believe that their lower limit of detectability by XRD is p0l.a1%ty ortallcessw.ith Byan ToEcMcaaslilontahlreefibPeernho-rwloeosds sthaamnpleosne shfiobweerd ;a per field. Th e y d o n 't regard this as significant and wou l d interpret this as no asbestos mineral by OSHA requirements. I We gave them three additional Penhorwood samples from our files for additional studies. We also discussed commercial talcs from other sources. They feel that R. T. Vanderbilt is c o m p l e t e l y "off the track" in their stand on OS H A regulations concerning asbestos minerals. They think it is on l y a matter of time until this stand completely destroys Vanderbilt. They described Jack Bartel's "emotional" interest in buying Desert Minerals Co. from J-M but believe that this will not happen because they view this business the same way we do the tremolite is too great a hinderance to marketing.

Influences A. External 1. Labeling-- During June of 1974 we discussed with various customers the possibility of labeling our talc products. This resulted in an immediate loss of some accounts. Letters were sent to our customers advising that the label would be affixed to our bags effective November 1, 1974. These letters were sent out in September of 1974. The | results of the letter in September and the actual labeling November 1 caused a further loss of customers. Our estimate of lost business on an annual basis was approximately 30 percent of our tonnage and 40 percent of our dollar volume. Please refer to my attached letter to P. Kotin which shows this effect. R. T. Vanderbilt and Pfizer (California talc) are not labeling. R. T. Vanderbilt is certifying their talcs are asbestos-free, but we have no knowledge that Pfizer is doing the same. We feel that Vanderbilt and Pfizer (California talc) will be required to label before the end of 1975. The adverse publicity generated concerning asbestos and tremolite has been such that even if we could remove the asbestos label from our talc, it would be some extended period of time, possiniy a year or more, before we could regain business lost to asbestos-free talcs. 2. OSHA and NIOSH-- Jointly studying asbestos in talc. OSHA has requested NIOSH to study asbestos in commercial talc, and NIOSH is studying asbestos content of talc mines with MESA. NIOSH considers all particles of chrysotile and the amphiboles that have three-to-one aspect ratio and over 5 as asbestos fibers. We expect increased activity from state (particularly California) OSHA offices on our talc customers because of tremolite. 3. PDA-- Does not appear to be a problem at the moment. Thair position stated in.the Federal Register March 14, 1975 withdraws their proposed ban of talc in food packaging. The proposed ban drew attention to asbestos in talc and we will have an uphill battle to get back market share we lost. CRMC-LLF-Pfizer-Micro-000027 4. General Market Conditions-- See Talc Sales attached a. Our ceramic and tile business remains relatively strong in spite of our problems. b. Paint is weak due to the economy and our tremolite/labeling problems. c. Our plastic business has all but disappeared due to the tremolite problem with the exception of Solo Cup which we started to sell in October of 1974. Solo remains strong but tremolite and the label are an ever present potential problem. Competition from Pfizer is fierce but we manage to hold on because Solo likes our product. d. Tremolite, the label, and quality, plus a poor business climate have combined to hurt our sales to the paper industry. Competitors from Montana talcs have been only too eager to point out to our customers that our talcs contain asbestos fiber. This is very rough competition, and coupled with the economy and quality problems, makes for difficult marketing conditions, to say the least. e. Price increases-- Ke had planned a six percent price increase for talc on an annual basis. We have implemented a three percent (annual basis) increase and have met great customer resistance. It is doubtful that a six percent will be achieved in 1975. A.decision to label by Vanderbilt and Pfizer could reduce the pressure on Desertalc and allow for selective price increases. B. Internal Influences 1. Ore Quality and Control Related to F.P.S.-- The problems with ore quality came about when we were forced to above ground mining. The lack of selective mining has caused virtually all of our problems con cerning brightness and acid solubles. The Mining Division is formulating a mining plan which should be completed soon to alleviate this oroblem. Problems encountered at the milling locations resulting in inability to meet F.P.S. stem primarily from the crude ore being shipped from Warm Springs. This, hopefully, will be corrected by the mining plan mentioned above. Other quality problems were caused by grinds being too coarse and poor plant management. Plans to train and adequately staff quality control personnel have been put into effect by Mining and Research. Plant management and supervision should CRMC-LLF-Pfizer-Micro-000028 improve dramatically when the Mining Division implements! their new organization plan for Desert Minerals on April 1, 1975. IV. Action That We Plan to Minimize Unfortunate Influences A. Tremolite and the Label-- We are and will continue to educate our customers on the necessity of proper dust control not only for asbestos fiber, but for all dust which is required by OSHA. Our industrial hygiene studies are very helpful in this respect. We believe and are attempting to convince the customers that they must clean up their plants and control dust to comply with OSHA regulations. By so doing, he eliminates the problem of asbestos. Wherever possible, we discuss bulk shipments to avoid dust problems. B. Ore Quality-- This problem is critical and compounds our problems with tremolite and the label. We are in constant contact with the Mining Division and communicating our problems in this regard. The formu lation and implementation of a good sound mining program, properly supervised, will eliminate this problem area. C. Quality Control Problems at Grindinq Locations-- Good quality crude is paramount, as it is the one area that the grinding plants have no control over. The training of plant quality control personnel so they know what they are looking for and can interpret their results properly will alleviate the problems of coarse grind. This, with better plant management which should be accomplished with the new plant organization, should reduce these problems to a minimum. T. E. Remmers has been assigned the responsibility of the key marketing liaison person to work and communicate to the Mining Division and to follow problem areas through. V. Recommendations The initial crunch of lost business due to the label has been felt. Our business seems to have stabilized. We expect further erosion in paint and possibly the loss of Solo Cup in plastics. Our ceramic business remains strong. We believe we can regain some lost paper tonnage with improved quality from Warm Springs and the grinding locations. During April we will phase out production from Los Angeles and move all production to Dunn. Some Cyclo-Fil may have to be made at Los Angeles on an intermittent basis due to capacities at Dunn. The consolidation of virtually all production at Dunn will cause Dunn to run at capacity for six-day weeks. The concentration of managerial personnel at Dunn should improve the plant's efficiency and eliminate CRMC-LLF-Pfizer-Micro-000029 many quality, shipping, and outage problems we have been experiencing. The costs used to arrive at net earnings with the revised forecast were submitted by the Mining Division. The cost includes the fixed cost for the Los Angeles Plant, which are estimated at $200,000 per year while closed down. If we were to dispose of this plant the fixed cost would be eliminated. The cost of operating Dunn and Warm Springs, in my judgment, appear to be overstated. We have never operated Dunn at full capacity with full management capa bilities which should insure better efficiency. We believe we still have a 45,000-plus ton per year business. Mining Division believes this business concentrated at Dunn will improve our profitability. We would like to stay in the California talc business at least until Penhorwood comes on stream, to maintain continuity in the market. The Desert Minerals operation should be reviewed for profitability progress after May results are in. If this business, with the changes contemplated over the next two months, can be made profitable, it will remain a good small business as Penhorwood should have virtually n o effect on Desert Minerals. CRMC-LLF-Pfizer-Micro-000030 CONFIDENTIAL - FOR J-M INTERNAL USE ONLY To: P . A. Martinson - 2W Data: March 20, 1975 From: R. S. Lamar - 2W Copie: J. M. Fletcher - 2S R. Keefe - 2W J. M. Sharratt - 2S Subject: AN ASSESSMENT OF THE J-M POSITION WITH TALC Three years since J-M's entry into the talc business with the acquisition of Desert Minerals Company is time enough for an appraisal of our position. This assessment is broken down into eight sections as follows: 1. The Effects of Labeling: Our position here has been the only acceptable action J-M could take. According to the definitions that are a part of the law, our California talc products all contain asbestos in the form of tremolite. No play on words will change this fact. mmmm mm mm j I mm mm mm mm -- V - > m-- a. -- -- .. . - * ... - . r. J..I the uniquely high brightness and relatively low acid soluble content of G-l and G-2 talc ores, we could hold onto most of the critical markets, in spite of labeling. I now seriously doubt our ability to do this. The "talc-asbestos" problem is quite different from the "asbestos-asbestos" problem. In many applications foT asbestos, there are no acceptable substitutes. With our asbestos-containing talc, there are numerous possibilities for substitution: (a) Non-asbestos containing talcs from both Pfizer and Cyprus from Montana sources and (b) Other extender pigments such as kaolin and calcium carbonate (in paints, for example, and in paper filling uses). We see this type of substitution being made and long-established markets for Desertalc products evaporating in the process. P. A. Martinson Page Two 2, The R. T. Vanderbilt Position: Their position with respect to labeling must be deliberately perfidious; they cannot be this misinformed. Slim Thompson, their technical director, has a Ph.D. in mineralogy. At the moment, Vanderbilt is misleading their customers and confusing ours with their decision not to label. Ultimately, the truth will out, and they will be forced to label. Pfizer's position is the same with their California talcs, h'ith all asbestos-containing talcs labeled, far greater value and emphasis in the market will be applied to asbestos-free talcs. I seriously question the capacity of these asbestos-free talcs to satisfy the total market. Also, in some applications, the asbestos-fTee talcs are just not a suitable sub stitute quality-wise. For example, in ceramic wall tile (a major market for treraolitic talc) there are few, if any, asbestos-free talcs that show the same forming and firing properties. Penhorwood fires to a brown color due to high.iron content. G-l Fires white due to very low iron content. Nevertheless, it is a fact that the Montana talc (asbestos-free) business of both Cyprus Industrial Minerals and Pfizer is booming, while we are in the doldrums. 3. (Quality: Historically, talc mining has been a highgrading operation with selective mining required to maintain acceptable quality fir various uses. This type of selective mining teas done successfully for over 25 years at the Grantham Mine. Proper quality and uniformity of ore were seldom, if ever, problems and sizeable markets were built on this foundation of quality. The unique high brightness of Cyclo-Fil (951 G.E.) was, in the past, properly maintained and a good and profitable market developed for this product in paper filling. With the brightness of current quality Cyclo-Fil dipping as low as 89%, there is no way we are going to maintain this business. Clays and other fillers at half the price of Cyclo-Fil can and are being used. * ' P. A. Martinson Page Three Other quality considerations relating to high acid soluble content and improper grind have caused an erosion of our paper industry business until virtually nothing remains. 4. Markets: At one time (less than three years ago) sizeable markets for Descrtalc products existed in paper, paint, plastics, and ceramics. Both DT-51 and DT-57 were the most widely used fillers in 40% talcfilled polypropylene. We lost this business prior to labeling because of tremolite content. Many of our paint and paper accounts have been lest for the same reason and labeling has accelerated this loss. Labeling, plus the loss of proper quality, has been disastercus. Ceramic sales of DT-51 have been difficult to maintain. High acid soluble and water soluble contents of G-l ore have resulted in casting slip gelation and rheological problems. The high acid soluble content of current quality G-l and G-2 ore has increased the alum demand of Lulu Cywlu-Suib unu Cyclo-Fil in paper applications to the point where, even if we had proper brightness, a paper mill could not afford to use our products. I can foresee no markets that can be built or rebuilt under present conditions. 5. New Technology; Froth flotation will reduce the trerolite content of G-2 ore to less than 1%, but will not remove all of the tremolite. In such a wet process, acid leaching will increase brightness several points. HIMS could probably also be used to remove even paramagnetic material to improve brightness still further. Newly developed sand or attritor milling procedures can grind down to a maximum particle size of under 2 microns, but I believe that all of these new techniques are a waste of time as long as we have to label. Also, the relatively high mining costs at Warm Springs, plus the absence of adequate water for these wet processing methods makes the development of other sources more attractive.

Penhorwood: Based on detailed testing, we feel certain that Penhorwood talc can be developed as a major source for pitch control and should be directly competitive with Mistron Vapor (Cyprus Industrial Minerals Montana talc). Other markets may be developed for Penhorwood in plastics filling, elastomer reinforcement, and paint. Although in this latter use, the relatively low brightness of Penhorwood is going to be difficult to overcome. If higher brightness grades could be developed from the same mining area, additional markets would become available. In paint uses, wet color uniformity is a majoT considera tion and must be maintained with Penhorwood talc or any other extender pigment. Analyses of Penhorwood core samples suggest that this may become a major problem. 7. Other Worldwide Talc Sources: With the worldwide decline in the industrial use of tremolitic or asbestoscontaining talcs, sources for asbestos-free talc will surely become more valuable. Major sources for this type of ore exist in France, Italy, Spain, India, Red China and other parts of the world. Generally, all of these deposits are selectively mined. Only Finntalc and Johnson and Johnson are using froth flotation to separate talc products of acceptable quality. We will do the same at Penhorwood,' and the industry must move in this direction as deposits amendable to high-grading are depleted. Talc producing areas in California, Nevada, and Montana have been thoroughly--if not systematically and profes sionally explored. It is unlikely that new largescale talc-mining properties could be developed. However, this possibility should be explored--but only for asbestos-free materials. There would appear to be an opportunity for good geological work. P. A. Martinson Page Five 8. Conclusions and Recommendations a. Labeling, plus a general decline in quality, has caused a disasterous loss in J-M talc business. Some of this business might be regained in spite of labeling, providing we could re-establish prior high quality standards in both our mining and milling of these products. However, the effects of labeling will always place us in a serious competitive position. The economic viability of such an operation is also highly questionable. b. Until PenhoTwood is in operation, we should try to hold onto as much of our existing talc business as possible. Such a holding action will be difficult, expensive, and disheartening, but should be done. Penhorwood will not replace all existing markets for Grantham talc because of darker color and other differences. c. Beyond the development of Penhorwood, J-M should attempt to develop, on a worldwide scale, other asberto free sources for talc mineral. These will most surely become more valuable with time. It would be unfortunate, indeed, if we were to let our poor performance with Grantham talc interfere with J-M development of other worldwide talc sources under more desirable conditions. X >V\'V 'S'f MANPOWER.

Reference (a) requested Mere Island Naval Shipyard to examine four tal.a for asbestos content and for comparability to the Pfizer Microtalc CP 20-30 talc used to cake reformulated MIL-P-24441 paints. 2. The asbestos content of the talcs was determined by microscopic analy sis using dispersion staining. The oil absorptions are based on data reported by the National Paint and Coatings Association and by the talc suppliers. The oil absorptions vere determined according to ASIM D-2B1 which has a reproducibility of + 25Z. The results are as follows: Source Cyprus ttistron 139 Oil Absorption 33 Asbestos Content Slight amount of fibrous tremolite in one of tvo samples. Desert Minerals Talc Co., 36 El-Fine 80 Large amounts of fibrous tramolite preaant. Pfizer Mierotalc CP 20-30 29 Slight amount of fibrous tremolite la one of two ssmples tasted. R. T. Vanderbilt, Nytal 300 29 Large amounts of fibrous tramolite and a small amount of anthophyllite present. 3. The elxborne dust hazards of asbestos in paint are unknown. Asbestos fibers that are tightly bound into a .paint should not be a problem. However, when paints axe removed by dust generating methods, such as sanding or abrasive blasting, asbestos fibers could be released. Cried paints are brittle and the shattering actiou of abrasive removal could break tha paint vehicle away from the asbestos and release the fibers. El *. 134.05-Ser 376 > ' 9631 < Subj: Asbestos content of tslc suitable for use in HIL-P-24441 paint Tale Is a common paint Ingredient and is used in a wide variety of paints sold to the Navy. Some talcs are relatively free of asbestos while others may contain from 20 to 6CZ asbestos. Hence, it is safe to assume that all commissioned ships are coated with asbestos containing paints. The poten tial'for generating airborne asbestos particles during grinding, sanding, or abrasive blasting of ships coated with asbestos containing paints will depend on the amount of asbestos in the dried paint being removed. Unfortunately, there is no standard analytical method for measuring the asbestos content of dried paint and the actual amount of airborne asbestos released by surface preparation of such paints Is not known. 4. The potential problem of generating airborne asbestos particles during surface preparation can be prevented by: (a) prohibiting the use of high asbestos content tale in Navy formula paints and, (b) requiring the use of Navy formula paints whenever prartleal. However, this approach will not work for proprietary formulas such as those procured under TT-E-490 (silicone-alkyd topside paint). Standard analytical methods for measuring the asbestos content of paints do not exist and there is no accepted limit for the asbestos content of paints. Consequently, there is no way to establish and enforce practical asbestos limitations for proprietary paints. 5. based on these observations. It is recommended that: a. The airborne ashester generated during the surface preparation of high asbestos content peine* bo investigated. Such an invert!gr.tian will have to determine the airborne asbestos dusting hstard posed by using dif ferent surface preparation methods to remove paints of known asbestos con tent. A major parr, of such a task will be to develop analytical methods for determining the asbestos content of vet and dry paints. Enclosure (1) outlines a project to accomplish auch a study. b. Approve Mlstron 139 and Microtalc CP2030 for use in MIL-P-24441 paints. 6. Mare Island Naval Shipyard has trained personnel and equipment needed to accomplish the recommended task. Rowevar, no technical personnel are available for assignment to the teak at this tima. The potential airborne asbestos problem associated with asbestos containing paints should be Investigated. Mare Island is willing to support such a project to the fullest extent possible but cannot take the lead on such a task until FT 81. It is estimated the project can be completed within 12 months for $75,000. \ M.'l.

October 4: Joint m eeting of C elite D ivision, Environ mental Departments and L egal Department to define plans of action for: A. Postponement and elim ination of proposed amendment to P art 121 (Food additives) of the F ed eral Food and Drug A ct incorporating the phrase "free of asbestiform m inerals" after the word talc relating to food or food packaging m aterial. B. E stab lish in g a v a ria n ce or am endm ent to OSHA regulation s P art 1910 to elim inate or modify the term s concerning trem olite a s related to asbestos fibers,and C. Develop a positive marketing program to ensure against deterioration of our talc market because of existing regulations. A draft of letter authored by Dick C arter directed to the Depart m ent of HEW edited and finalized and subsequently m ailed under date of October 3 requesting six-m onth postponement for prepar- . ation of documents concerning proposed regulation. Initiated action'on follow, up documents and data concerning five areas of activity: 1. Definition of asbestiform p articles. 2. M easurement of content, siz e , and identification of particles contained in talc. LA112 IIII III~II CRMC-LLF-Pfizer-Micro-000072 Memo to H. R. Keefe D ecem ber 13, 1972, page 2 3. M igration studies from paper food packaging m aterial. 4. P ro cessin g to rem ove asb estifo rm p articles. 5. M edical evidence concerning carcinogenic asp ects. Develop plans and action concerning OSHA regulations in relation to reclassification , com petition, bag labeling, and m arketing program . m Second m eetin g. O ctober 12, 1972; R&D m arketing con feren ce concerning new product development or product m odification program compatible with regulations. Further development program for m igration studies on paper, p la stic s, and coatings. Initiated plans to develop densified products (p ellets), slurry sy stem s, binder sy stem s, and new products conform ing to OSHA stan d ard s. Third m eeting, November 9i M eeting with Dr. George Wright exploring m edical asp ects of FDA proposed regulations and OSHA standards. Develop program for literature search into biological studies epidem iological considerations and other m edical asp ects. Fourth m eeting, November 28, 1972; Update a ll program s in progress concerning five areas of study regarding FDA proposal. A ll studies program ed for conclusion by D ecem ber 30, intending fir st draft of documents to be prepared early January. Fifth m eeting scheduled Decem ber 18; For prelim inary preparation of reports. Although no official word has been received concerning the postpone ment of the FDA deadline for com m ents on the regulations, com muni cations with FDA in Washington indicate that the six-m onth postpone ment w ill be secured. Approximately 30 responses received at FDA have been forwarded to C arter's office reinforcing the fact that additional study is needed before an appropriate regulation can be defined. P re lim inary reports, of m igration studies indicate no m igration at com m ercial lev els'o f usage of talc in food packaging papers. M edical literature search to date is developing a favorable case for lack of evidence supporting original.claim of carcinogenic influence as defined. A s to OSHA regu lation s, two environm ental studies of u se conditions have been com pleted at Lompoc and a third study is in p rogress. Conclusions of these studies resulted in corporate approval of a m ar keting letter dated October 24 concerning usage of DESERTALC and CYGLONIZED products in relation to airborne contam ination and fiber count.

So-called "eastern" talc tends to be fibrous, 'while In 1971, total market was 875,000 tons, and nearly $25,000,000 During the 1960 decade, ton sales increased at a rate of about 4%; dollar sales at a rate of 5*2%. ' . Major uses are in ceramics, paint, paper, plastics;--insecticidesand roofing. Paint and paper applications have shown the greatest recent growth -- up 54% and 112% respectively in the last decade. Growth has been most rapid in highly processed, highest priced specialty markets, particularly in the past few years. Talc Quality Processed (ground) talc in general has commercial, utility as an inert filler/extender pigment because of ... color (whiteness) ... low abrasion (relative) LA112 CRMC-LLF-Pfizer-Micro-000078 chrmical purity Desertalc is recognized world-wide as one of the brightest. Desertalo is recognized world-wide as having low abrasion index and this relates to good chemical purity. Desertalc is non- _ ^ t fibrous, and as such has application where fibrous talcs are Grantham sales are 45,000 tons and $2,300,000 of ground talc 6% of tons and 9% of the dollar market. Grantham also sells 25,000 tons ($700,000) of crude talc to the United Sierra Division of Cyprus Mines. The "opened" tale mines at warm Springs number three. Two are being worked at this time. Based upon geological data furnished by Grantham, together with Johns-Manville mining 1.5 million tons^ 2.7 million tons 2.1 million tons 2.5 million tons L A J 2 C R M C -LLF-Pfizer-M icro-000079 Some portion of tonnage between yross and recoverable may be mineable. A drill program would dictate action to be taken. At current and forecasted withdrawal rate, reserves are Clay reserves at Mohave, California, are estimated in excess of one million mineable tons. At current and forecasted annual Grantham's current employment is approximately 65 hourly and 15 salaried employees. Key people in the latter are, and each of whom very probably would join J-M: Rplf F. Bassett - Finance-Management - Age 60 Richard Lamar - r&d - Age 50 . Earl Smith Mining Norman B. Scheffel Daniel B. Tash * Now on contract with Grantham Included in this group are considerable talents and capabilities related to the talc business, resulting from years of exposure in Grantham and formerly with other western talc businesses. We plan also to have, a five-year Consultant Contract with W. B. Grantham for $60,000 per year. LATI 2 CRMC-LLF-Pfizer-Micro-000080  . , . .;!w: m - `5 - Mines The Warm Springs Canyon tala mining operation includes 80 lode claims. Not all are being worked. Those that are not are adjacent to- or contiguous with those that are worked. By virtue of the "Apex Law" as related by Grantham mining engineers, additional claims are included. The Apex basis is that any ore * body continuous beyond an established claim is considered to have common ownership. The Warm Springs operation is in Inyo county, California (lower Death Valley) and is 130 miles to union pacific rail head (Field or Dunn Siding, California) 140 miles to Las Vegas, Nevada 300 miles to Los Angeles The Warm Springs operation includes Diesel-operated electrical generation (no outside power); mt Well equipped base-camp living and recreation facilities, including outside swimming pool; An ample source of spring-fed fresh water supply; E & R facilities. Ore is hauled by contract carrier from Warm Springs to rail head. Mining is a">T underground, using room and pillar method. mfciii-' m The clay operation is- at Jaw Bone Canyon, Kern County, California. From mine to rail head (Southern Pacific - cantel, California) is C R M C -L L F -P fiz e r-M ic ro -000081 pm - 6- .11 miles. Ovo is contract mined and hauled, contract included in tha "Grantham package" calls for availability until "mine is exhausted." Mining is all open pit. Dunn Option Johns-Manville has option to purchase plant, auxiliary buildings and land (approximately 280 acres) from Pfizer. The latter acquired the total facility in 1967 from Kennedy Minerals, including tale mines. Pfizer had at the time milling facilities at Victorville, California, and a second plant was soon considered excess. The Dunn plant has been operated off and on during the past few years. Lompoc plant engineers have surveyed and ;arained the Dunn facilities and concur with the option list of equipment and facilities in general. Option expires in late February 1972. * Financial Projection - S Years Sales Grantham's sales, limited by capacity, re $3.0 million -- 956 of the market. Using Grantham's high quality talc and our sales force in our markets, we plan a vigorous expansion to $5.2 million sales in 1976, attaining 14% of the market. I "to:'.-'si-- CRMC-LLF-Pfizer-Micro-000082 ~i^o -J We plan $80,000 of earnings the first year (current level), growing to ovea?-$5 O0700 by 1976. I*ffcsJ ***t/ Grantham now we have used 35% after that Investment and Cash Flow Of the $6.3 million requested,y$5. million will be spent now. I 'Jr* In the next few years, we schedule $9.00^000 more -- with present forecasts, most of this in 1975 and 1976. At the end of the first year we will be out $5*0 million in cash flow, in the next few years we expect to pay for the future expansion and generate a positive flow of $2<2f"million We do not pretend to know the long-run future of talc or our participation, but we believe we can eventually attain sales of $10,000,000 and earnings of $1,000,000. However, if we can hold our sales and earnings after 1976, we will attain a. DCF yield of lllT on this venture. *l LA112 C R M C -LLF-Pfizer-M icro-000083 Geology - Chemical - Health Aspects Geologically, Grantham talc is in the Crystal Spring Formation (part of the pahrump Group in Death Valley) of the Panamint Range. There are three principal layers of ore bodies. There are outcroppings of the ore bodies, and portals are located at these points.' Ore strata are separated by dolomitic, diabase and volcanic rock formation. There are faults in the deposit which have been established in terms of quarrying procedures. The mineable ore beds are 10-15 feet in thickness and lie with Chemically, the talc is essentially magnesium silicate. Minor composition is calcium carbonate, sodium carbonate and potassium oxide. Trace composition is oxide of aluminum, iron, titanium,' manganese and copper. ___ ------------------- --- Petrographically, talc is major; tremolite small,or minor; calcite trace to small No health cases are on record with working people -- mine or other -- related to dust or other exposure. % 11 ' C R M C -LLF-Pfizer-M icro-000084 portadly other (pnrtieularly United sierra Division, Cyprus Mines and Vanderbilt) have had no cases related to environmental exposure. -w S m rnm Grantham clay (on contract not ownership) is geological! a claystone highly siliceous in composition. Minor com] is aluminum and potassium oxide; trace is oxide of iron calcium, magnesium and sodium The composition may be 1 considered an alminum silicate but not kaolinic in type 11treat as a nuisance dust V!)Mrf.V'.f '*' .

BAUMGARDNER I, Margaret J. Baumgardner, declare: 1. Ia m not a party to this action. I have personal knowledge of the facts set forth in this declaration, and if called as a witness, I could and would competently testify as to the truth of the matters set forth herein. 2. I am the Research Coordinator for the Claims Resolution Management Corporation ("CRMC"), a wholly owned subsidiary of the Manville Personal Injury Settlement Trust ("Trust"). The CRMC was created in December 1998 and is staffed by former Trust employees. On January 1, 1999, CRMC began providing claims resolution facility services to the Trust. 3. In this position, I manage the Asbestos Claims Research Facility ("Facility"), a document and records repository located'at 3390 Peoria Street, Suite 304, Aurora, Colorado. I am also the designated Records Custodian for the Facility. The Facility contains the business records including but not limited to correspondence, memoranda, reports, records and data compilations ("record") of Manville Corporation or related entities ("Manville"), generally, as well as Manville records relevant to litigation of asbestos liability. The records found at the Facility were transferred from Manville to the Trust beginning in November 28, 1988, the date on which the Manville bankruptcy plan was consummated. Additional records have been and continue to be transferred Q directly to the Facility. The Facility's records have been in the custody and control of counsel for the Trust or Trust personnel since the date of consummation. 4. My experience and familiarity with the documents at the Facility began in 1983 while working for Manville. In my work as a paralegal for Manville, I assisted in locating, indexing and packing many of the records which became the foundation documents for the Facility. I continued to work for Manville until September 1987. From March 1988 to September 1988, I was hired to supervise and assist in the indexing of the first 20,000 boxes which were turned over to the Trust in November 1988. From September 1988 to January 1989, I assisted in the privilege review of documents to be given to the Trust. From November 1988 to April 1994,1 worked for Freeborn & Peters and was put in charge of the Facility, managing all productions and "new" acquisitions. Declaration of Margaret J. Baumgardner Page 1 In September 1995,1 was hired by the Trust to manage the Facility. In December 1998,1 was hired by the CRMC to manage the Facility for the Trust. Accordingly, I am personally familiar with many of the records stored at the Facility, as well as how the records have been gathered. 5. To the best of my knowledge, information and belief, I certify that these records were made at or near the time by, or from information transmitted by, a person with knowledge, were kept in the course of the regularly conducted business activity of Manville, and it was the regular practice and the business activity of Manville to make the records. 6. Attached are documents found among the microfilm collections at the Facility. These documents, bates labeled CRMC-LLF-Pfizer-Micro-000001 through CRMC-LLF-Pfizer-Micro-000093 are true and correct copies of documents found at the Facility. I declare under penalty of perjury under the laws of the State of California and the State of Colorado that the foregoing is true and correct. Executed on August 10, 2015 in Aurora, Colorado.
